Two directories documented one concept (pi npm packages): top-level packages/ (browser-use, permission-system) and pi/packages/ (peon, web-access, subagents). Merged into pi/packages/ — one row per package in a single index, detail pages kept as archive records. The root index's 'OMP packages and skills' section was doubly wrong (packages/ was pi, not OMP); it becomes a Skills tooling section pointing at the consolidated /skills/ tree. Moved the two LIVE omp pages out of the retired-harness banner: pi/statusline.md -> core/statusline.md, pi/subagent-limits.md -> core/subagent-limits.md (both document omp behavior against agent/config.yml + the installed bundle; pi/index.md itself admitted the mis-shelf). Retargeted every inbound link (core/index, system/ dankserver, log x2, pi/index, settings x2, moved files' own xrefs). Refs #29

[pi-browser-use](https://github.com/TGYD-helige/pi) is a pi-coding-agent extension that wraps [chrome-devtools-mcp](https://github.com/ChromeDevTools/chrome-devtools-mcp), exposing all browser automation tools with a unified `browser_` prefix.

|
## Features
|
|
|
|
- **Dynamic tool discovery** — auto-proxies all upstream chrome-devtools-mcp tools with `browser_` prefix
|
|
- **Tool description augmentation** — adds usage hints for key tools
|
|
- **Result post-processing** — strips embedded snapshots, detects overlay/stale element issues
|
|
- **Optional visual analysis** — `browser_analyze_screenshot` via configurable vision model
|
|
- **Standalone mode** — runnable as independent MCP server via CLI
|
|
|
|

|
|
| `browser_fill` | Does not work on canvas/custom widgets |
|
|
| `browser_press_key` | Accepts single key name only |
|
|
| `browser_take_snapshot` | Call first to get uids, and after every state-changing action |
